IMPROVEMENT IN THE MANUFACTURE OF BROOMS.

The Schedule referred to in these Letters Patent-and making part ofthe's'ame.

To all whom it 'mayl concern Be it known that I, EzuA l). MARBLE, ofSuffolk Centre, in the county of Worcester and State of Massachusetts,have invented a new and valuable Improve` ment in the Manufacture ofBrooms; and I flohereby declare that the following is a full, clear, andexact description of the construction and operation of the same,reference being had to the annexed drawing making apart of thisspecifica-tion, and to the letters and gures of reference markedthereon.

v Figure 1 of the drawing is a representation of the cortex.

tured.

Figure 3 is a representation of the bark slit.

My invention has relation to the utilization of the stalk of broom-cornbelow the top or straw; and

It consists in thenovel method of preparing it, whereby it becomesserviceable in the manufacture of brushes,

.b1-ooms, and other articles of like nature.

The envelope or cortical portion of the broom-corn stalk is highlysilicious, and yet-very elastic, rendering it very suitable for theobjectin view when properly prepared. p

After the top'ior straw has been removed the stalk is cut into suitablelengths. Each length is'then cut Figure-2 is av representation of abrush manufacopen longitudinally, and the pith carefully removed withoutinjuring the inner surface of the cortex. Thus prepared, the bark orcortex is shown at iig. l of the drawing. y

The next step is to slit the bark or cortex longitudiually,'carrying thedivisions from one .end nearly but not quite to -the other, as shown infigr of the drawing.

The sections are now rolled up, by means of their undivided ends, andare ready for attachment to the brush-body or broom-handle.

My invention is designed to effect a great saving in the manufacture ofbrooms, brushes, 85e., and will makethese articles more plentiful.

IVhat I claim as my invention, and desire to secure by Letters Patent,is-

In the manufacture ofbrooms and brushes, the' utilization of thecortical envelope of the broom-corn stalk, substantially as specified.

In testimony that I claim the above I ha e hereunto subscribed my namein the presence of wo wit.-
